PARTITION.

SPECIFICATION forming part of Letters Patent N0. datedoetober 1900- Application filed May 22, 1900. Serial No. 17,523. (No model.)

To all whom it may concern:

Be it known that I, HARRY W. BELL, a citizen of the United States, residingin the borough of Manhattan, in the city and county of New York and State of New York, have invented certain new and useful Improvements in Partitions, of which the following is a specification.

This invention relates to the construction of partitions or walls, and more particularly to the construction of shafts, such as dumbwaiter shafts,one object of the invention being to provide an improved fireproof structure of this character formed of improved blocks or components connected at their corners by an improved binder or coupling.

A further object of the invention is to provide an improved partition block or component particularly adapted for use in the building of shafts-such, for instance, as dumb-waiter shafts.

A further object of the invention is to provide an improved binder particularly adapted for use in connecting partition blocks or components when assembled to form an angular structure.

In the drawings accompanying and forming a part of this specification, Figure 1 is a perspective view of a dumb-waiter shaft, illustrating the present improvement. Fig. 2 is a top view of one corner thereof. Fig. 3 is a view of one form of binder which may be used, and Fig. 4 is a View of another form of binder.

Similar characters of reference designate like parts in the different figures of the drawlngs. v

In practice each of the blocks or wall components 2 of which the shaft is composed may be formed of any suitable material to render it fireproof and of any suitable shape and size. In the form shown each of the blocks 2 is preferably of greater length than breadth, the blocks being preferably constructed of such size that each will be of a length to form the side or end of the shaft, as the case may be. In practice each of these blocks 2 is provided along one or both of its longitudinal edges, preferably along both such edges, with grooves or depressions 4:, shown as curved in cross-section, and each block is provided at a predetermined disblocks or wall components of the structure which overlap the ends of an intermediate block or wall component are provided with transverselyextending grooves or depressions 6, each intersecting or extending transversely to the longitudinal groove 4, adjacent to the outer end thereof, whereby such trans-v versely-extending grooves 6 form continuations of the longitudinal grooves formed in those blocks, the ends of which are overlapped by the blocks having such transverselyextending grooves. By this organization it will be seen that an angular recess 7 is thus formed, one part of which is formed by the longitudinal recess of one block and the other part by the transverse recess of said block and the longitudinal recess of its companion angularly-extending block.

To bind the blocks together at the corners thereof, an improved binder 8 is provided comprising an angularly-formed metallic member or iron formed with a pair of arms 8 and 8", bent at an angle to each other and shown herein substantially as a right angle. Each of these arms is provided with means for engaging in the openings or apertures 5. In one form thereof this means comprises projections 9, bent at an angle to such arms 8 and 8". In assembling the structure the wall components are disposed in rows or tiers, the blocks of one row being so located as to break joint with the blocks of the companion row or rowsthatis to say, one component, as 10, of one row will overlap the ends of one or more transversely-extending components, as 12, of the same row, while another component 10 of the next row will be overlapped by the ends of one or more transverselyextending components 12, the components which overlap at the ends being provided in each instance with the transversely-extending grooves or depressions 6. One row of components having been assembled in the proper manner, the corners of said components are united by means of this improved binder, which is placed in position with its arms resting in the angular recess 7 and its ends 9 projecting into the openings 5 formed in the blocks. In practice the binder maybe so located in position that a portion thereof will be received in the angular recess of the next or succeeding tier or row of blocks, thereby to bi nd all four of the blocks together at the corners. The binder may also be provided with means which will enter the openings in both tiers of wall components-as, for instance, by providing the arms 8' and 8 with bent ends or projections 9, which extend in opposite directions relatively tosuch arms. This may be accomplished in one form by bending the metal at the ends of the arms upon itself, substantially in the manner shown in Fig. 4, thereby to provide projections extending transversely of such arms, whereby one set of projections will enter the openings in one tier of components, while the other set of projections will enter the openings in the other tier of components, thus firmly uniting all four of such components together at the corner of the structure. By this improved organization the blocks are united at their corners to form a rigid construction, the blocks of one tier firmly united with those of another, so that the separation thereof is prevented even without the use of mortar or cement, which is, however, preferably used. The use of cement alone, however, as has been found in practice, is insufficient to firmly and rigidly unite the structure at its corners.

It will of course be understood that the unused portions of the grooves need not be formed, although when provided they constitute a means for the reception of the ocment, and thus more firmly lock the wall com ponents together.

Instead of providing the openings 5 during the manufacture of the blocks the ends of the binders can be easily forced into the blocks when such binders are assembled therewith.

I claim as my invention 1. A structure composed of a plurality of rows of wall components, the components of each row being assembled to form a corner or angle, and the components of one row breaking joint with the components of its companion row, and each of said components having one or more longitudinally-extending grooves, and some of said components having one or more transversely-extending grooves; and a binder comprising an angular member located at said corner in said grooves.

2.
